To all whom it may concern: I

Be it known that I, "WILLIAH D. FOR- srTi-I, a citizen of theUnitedlState's, residing at Youngstown, in the county of Mahoning andState of Ohio, have invented. a new and useful Metal lVindowJ rame, ofwhich the following is a specification. f

Myinvention relates to a new andlilseful form of metal window frames,adapted to be used in place of wood or other material here:

tofore used in making sashes for windows.

' to form the stiles or barsof the frame.

'My' invention consists in an improved metal window frame of easy andcheap manufacture, it is strong, flexible and adaptable in use in makingand operating windows.

My improved metal window frame is illustrated in the accompanyingdrawings in which Figure 1 is a. perspective view of the top molding ofmy window frame. Fig. 2 is another, view of the same top molding notchedfor the reception of the stiles or bars of a window-frame. Figs. 3 and 4are" perspective views of the metal sections used Fig." 5 at a is avertical cross section of 4 at see i tion line a a. Fig. 5 at Z) is ajoint formed i by 8 and 4 with 4 shown in elevation and 3 i in crosssection at a line flush with the web I of 4. Fig. 5 at 0 shows acrosssection of 3 at sectionline c c. Fig. 6 is a joint formed by 3 and 4with 3 in elevation and 4 in crossf secti'on at a line flush with thewebof 3. Fig. 5 7 is a perspective view of the joint of the' frame formedby the bars or stiles 3 and 4. Fig. 8 is a cross section of molding 2mounted upon stile 4. Fig. 9 is a cross section of I molding 2 and stile4, with the slips G, C, holding panes of glass in place; dotted linesshowing position of putty. Fig. 10 shows:

perspective view of molding 1- with a U section used for the stile orbar and substituted for the T section shown in the preceding figures.Fig. 11 shows the clip 0 in elevation and end view. Fig' 12 shows a.joint'in my improved window frame with T section used for the bars orstiles thereof and top molding attached thereto, part of saidnoldingbeing uotchedand continuous and the other part of said moldingbeing parted at said continuous molding.

:top molding. thus assembledwith the notched top mold- ,The to moldingof my improved frame andthe 'sction form tifthe' stiles or bars thereofare preferably formed by rolling metal to the cross section of saidmolding and the said T section of said stiles orbars shown in Figs. 1,2. 3, and 4. Aftersaid molding has been rolled of a suitable metal ofsuitable dimensions, it is-notched as at 2, Fig. 2, so that it may bepassed over the flange of 3 when the same is placed on 4 to form a jointas in Fig. 7 The bar or stile shown in Fig. 3 is preferably rolled in Tsection of suitable metal and dimensions and is notched at 3 as shown,in Fig. 3, so that it may he joined with baror stile 4. Bar or stile 4shown in Fig. 4 is made of suitable metal by rolling in the T sectionandis notched at 4 4, Fig. 4, so as. to form with 3 the oint or cross shownin Fig. 7. r

hen the T section stiles or bars 3 and 4' are notched and assembled by,placing them so that the notches therein coincide so as to form. thestructure shown in Fig. 7, with the top surface. of their flangesflushed with one another and with the bottom parts ofsaid flanges insubstantially the same plane'g thc top molding shown in Fig. 2 is placedlongitudinally with stile 4 so as the flange of 3 is inserted in thenotches 2 2 of said The bars or stiles 3 and 4 as ing 2 are placed in apress and the ends 2 2 of molding 2 are pressed around the flanges of 4as shown in Figs. 9 and 12. After stiles or bars 3 and 4 have been assembled in any desired number and the notched molding 2 is placedthereon and the ends thereof 2 2 are pressed around the flanges of saidstiles or bars 4, lengths of molding 1 are cut of siiflicient lengthsothat B of molding 2 in one member of the frame to the next adjacentmolding 2 over the next parallel stile of the' frame. Said short lengthsof molding 1, Fig. 12, are fitted and formed at both ends so as toconform to the lines and curves of molding 2. Said short lengths ofmolding 1 are then placed over the flanges of stile or bar 3 and theends 1 of said molding 1 are pressed around the flanges of stile 3. Whenthe T section stiles or bars 3 and 4am connected together at theirnotched portions and molding 2 is placed over the flanges'of stile orbar 4 and the ends of molding 2. pressed around the flanges of said barsand the short lengths of the bead 1 thereof will extend from bead .3,the construction shown in Fig; 12 results.

Clip C is. made of sheet metal and is pressed and cut in the shape shownin Fig. 11 when it is used in connection with my frame before the endsof moldings 1 and 2 are pressed around the flanges of 4 and 3respectively, said 'clip C is placed at intervals under said flanges andnext to the web of said stiles or bars3 and 4, and when the ends ofmoldings 1 and 2 are pressed around the' flanges of said bars or stiles,said ends are made to include the ends of said clip so as to form theconstruction shown in Fig. 9; putty may then be placed under the flangesof the stiles 3 and 4' so as to occupy the space shown in dotted lines,Fig. 9.

Fig. 10 shows a U shaped section substituted for the T. section of theother figures the clip C being substituted by the tongue T punched fromthe U shaped stile.

What I claim as my invention is:

1. In a metal window frame, the combination of series of stiles ofT-shaped sections,

inotehed in the lower edges of their webs; a

second series of stiles of 'T-shapecl section notched in their flangesand the upper portions of their webs, said series of stiles beingadapted when placed across one another and pressed together at theirrespective notches to form rectangular apertures in said window framewith the tops of the flanges of both of said series of bars beingsubstantiall in the same plane; continuous notched mol ings adapted tobe placed longitudinally along said .stiles having notched flanges andnotched in the upper portions of their webs and formed to pass over theunnotched flanges of the other series of stiles having webs notched attheir lower edges only, said continuous notched moldings havingdownwardly extending ends adapted to be bent around the flan es of thestiles having notched flanges an notches in the upper portions of theirwebs; and sectional moldings adapted to be placed over the flanges ofthe bars having notched webs only and having downwardly extending endsadapted to be bent around the flanges of said last mentioned bars, beingmade of such length and being fitted so as to extend along the stileshaving notched webs only between the lines of continuous moldin smounted upon the flanges of the stiles havlng notched flanges and webs.

glass-holding clips attached to the under.

side of the flanges of both of said series of bars by the downwardlyextending ends of said continuous and sectional moldings bent around theflanges of said bars; both of said series of T-sh'aped bars being sonotched as to webs and flanges that when placed across one another thetop surfaces of their flanges will be substantially on the same plane.

- 4. In a metal window frame the combination of series of T-shapednotched bars so 5. In a metal window frame the combina tion of .twoseries of T-shaped notched bars so formed that .when placed across oneanother at their notches, the top surfaces of their flanges will besubstantially in the same plane; withcontinnous to moldings notched attheir lower edges a ed to one ofthe series of said bars and sectionaltop moldings aflixed to the other series of said bars, between theparallellines of continuous top moldings, both of said moldings betionof two series of T-shaped bars notched s that when placed across oneanother the bottom surfaces of the flanges of both of said series ofbars adapted for the'reception of panes of glass are substantially inthe same plane and series of moldings mounted upon said series of bars,the one series of moldings being continuous and notched at their loweredges and attached to one series of bars, and the other series ofmoldings being sectional and extending between said continuous notchedmoldings and attached to the other series of bars 7 7. In a metal windowframe the combination of series of T-shaped bars notched so that whenplaced across one another the 0 bottom surfaces of the flanges of bothof said series of bars adapted for the reception of panesofglass aresubstantially in the same plane; series of moldings mounted upon saidserles of bars, the one serles of moldings being continuous and notchedat their lower edges and'the other series of moldings being sectionaland extending between said continuous notched moldings mounted .asaforesaid and glass-holding clips attached by the downwardly extendingends of said moldings to the under side of the flanges of said bars. v
